have just purchased new glasses and within 3 hours one lense fell out . During the night 10 hours later woke up and felt for them and both lenses fell out. Fortunately had my old set with me. On close inspection the screws were fully tightened so how can this happen, can only assume lenses machined too small for the frame. How could they be pushed back in very easily if frame is tight.How can this leave your workshop like this were is your QA, This not the first time that your work shop service has been at fault with my glasses over the years. Although we are living in difficult times I feel your company’s service to people who rely heavily on their eyes as been dreadfully. Opening hour and service could have been better managed.
